BAG FILTERS (BAGHOUSES) - Redecam Group

1 Bag FILTERS (baghouses) have been our core product for over 30 years. With our own proprietary technology, our Bag FILTERS offer the highest particulate removal efficiency on the market, far exceeding the most stringent emissions regulations worldwide. Our secret has been to constantly evolve with technology and search for improvements to provide our customers with optimum air filtration CHOOSE OUR BAG FILTERS ?Incomparable life expectancyWe have Bag FILTERS that were installed over 25 years ago that still achieve the strictest emission requirements solutionsOur persistent R&D has led to innovations such as our Dual- and Multi-Input Integrated Systems, saving CAPEX and casing tightnessOur SPS bag fixation system ensures 100% casing tightness, meaning no dust energy costsRedecam s Bi-Jet Bag Cleaning System reduces your system s compressed air usage by up to 40%, lowering energy temperature capacityWe offer Extreme High Temperature Bag FILTERS which can withstand temperatures of up to 1000 C (1832 F).

2 Unsurpassed filtrationOur Bag FILTERS can far exceed the strictest regulations and can remove more fine and ultra-fine particulates than any other on the FILTERS (BAGHOUSES) Bag FILTERS are suited for high flow rates (above million m3/hr or 883,000 ACFM) and medium inlet dust burden applications (up to 200 g/Nm3 or gr/ft3). Examples include installations with 3-fan kiln circuits, clinker coolers or our Dual-Input Integrated System, as well as solutions in large power plants or integrating flue gas treatment. This model has compartments placed in pairs on either side of a large central duct. The central duct contains separate ducts for the inlet (dirty) gas and the outlet (clean) gas.

3 The baffles (pipes and perforated plates) are specially designed for each project to ensure the ideal permeability and orientation in order to obtain a uniform gas velocity throughout each pair of compartments. As particles are captured, they enter hoppers through isolation dampers, designed to provide superior airflow control in severe DPD-Model Bag FilterBAG FILTER S: MODEL SWe offer a wide variety of Bag FILTERS and Nuisance FILTERS to suit any flow rate and dust burden. All models feature our innovative SPS bag fixation system and our Bi-Jet Bag Cleaning System, ensuring optimal air filtration and lower operating costs (SPS and Bi-Jet are optional on Nuisance FILTERS ).

4 All of our models are also available as retrofits, upgrades or transformations. Among our most popular models are our DPD- and DPM-Model Bag visit the Products section of our website at for information about our other Bag Filter the air-to-cloth ratio is of utmost importance for DPM-Model Bag FILTERS , the can velocity has no impact on the design since the gas flow to bags is horizontal. Access is made on one side of the bags in order to avoid the gas rising after mixing with the dropping Bag FILTERS are suitable for high flow rates (above million m3/hr or 883,000 ACFM) and high inlet dust burden applications (up to 1000 g/Nm3 or gr/ft3).

5 Examples include installations with 2-fan kiln systems, in cement mills or on separators. In such cases, there is a need for efficient dust pre-separation to reduce the dust burden reaching the wide central hopper is used to decrease the axial gas velocity so that a dust pre-dropping action takes place. Suitable baffles between the gas inlet and the central hopper ensure a uniform gas flow and velocity across the hopper cross-section. Indeed the gas, after being largely pre-separated of its dust, rises up in the central hopper and passes through our unique Distribution Screen, which acts as another dust separator. This screen disperses the gas/dust evenly throughout the filter bag compartments, resulting in a highly efficient process.

6 This translates into a lower pressure drop, fewer cleaning cycles, a longer bag lifetime and significant compressed air savings, meaning lower energy UNIQUE FEATURESOurDPM-ModelBag FilterBlow pipeSolidsCleaned gas outletBi-Jet Bag Cleaning SystemCageBagsSPS Tube SheetWe offer multiple Bag Filter models for flow rates from 10,000 m3 to 3,000,000 m3 (353,000 ft3 to 105,000,000 ft3) and for dust loads of 1 g to 1 kg ( oz to 35 oz). Redecam is a market leader in carrying out retrofit and transformation solutions: they are among our specialties. Many existing bag FILTERS and electrostatic precipitators (ESPs) have become obsolete, either due to their age or their lower performance than current standards require.

7 However in several cases, existing bag FILTERS can be upgraded or retrofitted (taking out what s inside, keeping the casing and installing new Redecam components inside).Transformations are also possible. This means changing an existing ESP into a Bag Filter, or : Lower CAPEX than replacing with a new model Emissions can be reduced to well under the world s strictest emissions limits Transformations can be made within the existing footprint Minimal ductwork modifications/additions Reuse of existing ancillary equipmentThis new technology extends our air pollution control offering, as our Extreme High Temperature Bag Filter (EHT-Bag Filter) can remove both solids and tars while withstanding temperatures of up to 850 C (1562 F).

8 It can even treat peak temperatures of up to 1000 C (1832 F).Our EHT-Bag FILTERS are therefore ideal for the Oil & Gas industry and offer benefits for certain applications in the Cement, Metals & Mining and Waste-to-Energy & biomass Power industries. Equipped with ceramic catalytic candles, our EHT-Bag FILTERS can be paired with our full flue gas treatment (FGT) system whether to treat acid gases, mercury and metals or NOX or all of these our innovations are systems in which one Redecam Bag Filter is used to dedust gases from two or more process or unit points to save our clients significant space and CAPEX.

9 Our Dual-Input Integrated System, developed for the cement industry, uses one Bag Filter to dedust both the kiln & raw mill and the clinker cooler. For the Metals & Mining and Oil & Gas industries, we created Multi-Input Integrated Systems, which collect flows from several process points or units and converge them into one Bag Filter (ex: converging the gases from the Electric Arc Furnace or another primary hot source with gases from a secondary cold source into one baghouse).OUR DUAL- A ND MULT I-INPUT INTEGRATED SYSTEMSOUR EXTREME HIGH TEMPERATURE BAG FILTEROUR SPECIALIZED RETROFIT & TRANSFORMATION SOLUTIONSS tackClean gasBag FilterHeat ExchangerKilnClinker coolerRaw millFanFanFresh airMixing OF OUR EXTREME HIGH TEMPERATURE BAG FILTER: Optimal performance.
